Caution
Intel PT virtualization is BROKEN, as it has multiple fatal flaws, several which put the host at risk. Use at your own risk.
This guide will most likely become obsolete once the feature will be removed from the various linux distros. For more info check out KVM: VMX: Mark Intel PT virtualization as BROKEN and CVE-2024-53135
This script sets KVM Processor Trace feature in host-guest mode enabling VMs to use intel-pt
Just a quick update before we dive in: what we're actually doing here is running Raspberry Pi OS (64-bit) on a QEMU virtual ARM setup. This isn't full-blown hardware emulation of the Raspberry Pi 4, but more about creating a virtual environment for the OS. It doesn't mimic all the specific hardware features of the Pi 4, but it's pretty useful and great for general testing. I turned to this solution mainly to extract a modified sysroot from the Raspberry Pi OS, something not readily available in other resources. For those looking into detailed emulation of the actual Raspberry Pi 4's hardware in QEMU, check out this link for the latest updates: https://gitlab.com/qemu-project/qemu/-/issues/1208.
Hope it helps! :D
